Product Introduction
Gas Hot Water Heating Solution

The Gas Heating Hot Water Stove showcases a sophisticated, contemporary design that merges elegance with practicality. Its main body features a large, frosted glass panel in a soft, muted beige tone, which adds a high-end, minimalist aesthetic while resisting fingerprints and scratches—ideal for long-term use in busy households.

The lower section integrates a sleek digital control area: a bright LED display shows the current water temperature and the set temperature. Between them sits a circular analog clock and touch-sensitive buttons for power, mode, and temperature adjustment, creating an intuitive interface. The compact, wall-mounted structure ensures it occupies minimal space, making it suitable for apartments or homes with limited utility room area.

Frequently Asked Questions
How do I choose the right power for my home?
For residential buildings of 80-150sqm, 24KW is ideal for one kitchen and two bathrooms. For 150sqm+ or villas, choose 28KW or above. In colder regions or poorly insulated homes, consider increasing power by 20-30%.
Can it provide heating and hot water at the same time?
The system prioritizes hot water. When a hot water faucet is opened, heating is temporarily suspended and automatically resumes once the faucet is closed.
Is a condensing boiler worth the extra cost?
Yes. Condensing boilers achieve over 107% thermal efficiency, saving 15-20% on gas compared to standard models. This energy saving typically covers the price difference over long-term use.
Can I install this in an old house without pre-installed pipes?
Yes. You can opt for an open-air radiator system which doesn't require damaging walls or existing decoration. It features a short construction period and maintains a clean aesthetic.
How does the anti-freezing mode work in winter?
If you are away for a short time, keep power and gas on; the equipment will automatically maintain a low temperature to prevent freezing. For long absences, it is recommended to drain all water from the machine and pipes.
Does the boiler consume a lot of electricity?
No. The main power components (fan and pump) use only 100-200W and do not run continuously. The monthly power consumption is comparable to a standard household refrigerator.
